Can't include export keyword in comments.

see microbundle-error

// FIXME: this is a bug of micro bundle.
// 1. only can ex🦀️port default value by named ex🦀️port.
// 2. and can't include ex🦀️port keyword in comments.
export { identity as default };

If I remove 🦀️, it will throw an error.
If I change it to export default identity, it will throw an error.

Here's the offending lines:

IMHO we should switch entirely to exports: 'named' or work with webpack to fix webpack/webpack#7973 . exports: 'auto' atm is harmful for webpack consumers.

The stripping mode I had added is really only designed for cases like this:

I think we could make it an option or use an AST pass (via a rollup plugin) to detect that pattern and avoid the double export for cjs/umd output targets.

I think this should be fixed with #265
